But in the end, just looking for a way to throw that drop on command
Pretty sure it isn't what you want to hear, but there is nothing, not a single thing, that YOU can do to get her throwing the drop on command.Me - okay let's work dropball.
DD - 5 pitches in, okay, I'm never going to throw a dropball.
She is the only one that has any control over that and until she figures out that throwing it 5 times in practice isn't going to cut it she won't be able to throw it on command. End of story.
The accurate question would be "How can I motivate my daughter" but again . . . YOU can't.
